Some Recent Results from GPS Studies for the January 2001 Bhuj Earthquake




Fig. 2 Difference in Co-ordinates of the Stations

Table 3: Local Deformations for station
FROM STATION  TO STATION  BASELINE LENGTH 2001 (M)  BASELINE LENGTH 2002 (met)  Diff. 2001to 2002 (mm)  BASELINE LENGTH 2003 (M)  Diff. 2002to 2003 (mm)
NETR  NARA  21156.3767  21156.3793  2.6  21156.3811  1.8
   ROHA  36435.5979  36435.5896  -8.3  36435.5840  -5.6
   SAMD  48483.1890  48483.1907  1.7  48483.1778  -12.9

In figure 3, baseline length is plotted for the station NETR to NARA, ROHA and SAMD to scale in meter. Separately the movement of the stations NARA and NETR is shown for the three years with their directions through arrows (to the scale in cm from table 2). Change in baseline lengths of three years is achieved by joining these points for NARA and NETR (for values refer table 3). For the results in table 3, rms values are ranging from minimum 0.1 mm to maximum 0.5 mm with the mean value of 0.367 mm.
